Why couple models

Crystal Clear action info.png

Earth science questions often are not just about one specific process or domain. There are complex interactions and connections between different processes that you may want to explore. Models are often designed by experts on one set of processes or on one domain; coupling of models allows you to connect your model to other detailed models to form new connections and then address new science questions.

About CMT


The CSDMS Web Modeling Tool (WMT) is the web-based successor to the desktop CSDMS Modeling Tool (CMT). WMT provides a user-friendly interface to the CSDMS supercomputer that allows users to run components from the CSDMS model repository in standalone mode, or couple them with other components to create new models. WMT runs on any device with a web browser: a desktop computer, a laptop, a tablet, or even a mobile phone. WMT offers users a simple visual technique for performing surface dynamics model experiments on a supercomputer.

Download the CSDMS Modeling Tool (CMT) client for PC, Mac or Linux and start running models or coupled components on the CSDMS supercomputer.

The CSDMS Modeling Tool is your way of communicating with the CSDMS supercomputer. Scripts and commands constantly go back and forth between the CMT on your computer and the HPCC. Read more about three prerequisits in the above section.

Run models


We have a database with all models that are components in the CMT. Provided you have already setup the required HPCC account and a secure connection you can launch the CMT quickly from the list.

Visualization output


Model simulations in the CMT are setup to generate output that can be visualized with the associated software package VisIT. VisIt can run remotely on the CSDMS HPCC, but you do need to install the package on your own computer to fully use this functionality.
